A winter, many iPhone will appear fast power consumption, and even automatically shut down and other issues this year after upgrading iOS 11 system, the iPhone even worse problem. In this regard, you guess how to solve Apple - that is, the processor speed limit , Which is to reduce the poor battery performance of the old iPhone running speed.
A few days ago Reddit forum netizens revealed that the third-party agency Primate Labs after the benchmark test of the old iPhone models found that 'Apple is reducing the old iPhone performance', and after replacing the battery, iPhone significantly accelerated and then speculated that 'Apple is In order for consumers to buy a new iPhone deliberately slow down the old iPhone '.
Now, Apple officially released a statement 'admitting to limit the processor speed to prevent the iPhone from shutting down' and said 'our goal is to provide consumers with the best experience, including the overall performance of the phone and extend its useful life in cold weather, With aging, the ability of lithium batteries to provide short-term peak currents will diminish and their discharges will drop, which will result in accidental shutdown of the device in order to protect electronic components.
In the statement, Apple also referred to the iOS 10.2.1 update package designed to address shutdown problems related to battery output voltage. "Apple introduced a new feature last year for iPhone 6, iPhone 6S and iPhone SE, In those cases, the peak current is smoothed out to prevent sudden device shutdowns, and in the iOS 11.2 operating system, Apple extends this feature to the iPhone 7 and plans to extend this capability to more devices.
Apple internal sources have said that lithium-ion battery technology relies on chemical reactions, have a certain life, while the degree of performance reduction iPhone depends on the degree of battery loss, use, charge / discharge cycles and temperature will cause lithium-ion battery loss .
